Abstract: A method for producing an arrangement is provided. The arrangement includes a plurality of layers, whereby an organic layer is formed on a surface of a semiconductor substrate, under the influence of irradiated light, by applying a medium containing an organic substance to the surface of the semiconductor substrate, and deposition of the organic substance. A difference in potential is created between the semiconductor substrate and the medium during the deposition of the organic substance, by applying an electrical voltage. The invention also relates to a biosensor comprising an arrangement of a plurality of layers, and to a method for measuring properties of a test constituent using the biosensor. The arrangement of a plurality of layers comprises a semiconductor substrate layer and a layer which is arranged adjacent to the semiconductor substrate layer and contains a biologically active constituent.
